• MICRF114 Wireless Remote Key Fob

• CR2032 Coin Cell Battery

• SX1239 Receiver PICtail Daughter Board

• Embedded Security Development Board

• USB-A to Mini-B Cable

This cable is used to power the Embedded Security Development Board. Power can also be provided by a bench power supply.

2.3 SOFTWARE REQUIREMENTS

The MICRF114 Wireless Remote Key Fob and Embedded Security Development Board are preprogrammed with a remote control demo program. Section 2.4 “Demo Setup” and Section 2.5 “Demo Operation” explain the demo setup and operation.

For additional information related to the demo, visit the MICRF114 product web page at www.microchip.com/MICRF114.

2.4 DEMO SETUP

To setup and operate the remote control demo program, perform the following steps:

1. Open the plastic enclosure of the red key fob by carefully prying apart the two sections. Carefully remove the Printed Circuit Board (PCB) from the plastic enclosure. Observe the correct battery polarity and insert the CR2032 coin bat-tery into the battery holder. Put the PCB back into the plastic enclosure and then close the enclosure.

2. Press any push button to verify that the key fob is properly installed. The LED flashes when the button is pressed.

3. Plug in the RF receiver daughter board into the PICtail socket of the Embedded Security Development Board. Ensure that the RF receiver chip side faces the center as shown in Figure 2-1.


http://www.microchip.com/MICRF114


FIGURE 2-1: PLUG THE SX1239 RECEIVER PICtail™ DAUGHTER BOARD INTO THE EMBEDDED SECURITY DEVELOPMENT BOARD

4. Power-up the Embedded Security Development Board.

To power the Embedded Security Development Board from the USB port, con-nect the USB-A to Mini-B cable and an available USB port or USB power source to the development board. Set jumper J6 to pins 1-2. When using a USB port for power, loading the USB drivers is not required.

To power the Embedded Security Development Board from an external power supply, connect test points labeled +VEXT and GND to a bench power supply set to 3.3 VDC. Set jumper J6 to pins 2-3.

Once the Embedded Security Development Board is powered up, the messages “Security and Auth Development Kit” followed by “KEELOQ 3 Demo 433.92 MHz” appears on the LCD display. If the second message did not appear within five seconds, press the MCLR button located on the upper right quarter of the board.

2.5 DEMO OPERATION

The preprogrammed demo is used to demonstrate the basic operation of Microchip Remote Keyless Entry (RKE) solutions. The demo highlights the capabilities of secure data transmission over the air. Two different methods of securing information before transmission, KEELOQ Classic and KEELOQ AES, are used in this demo.

2.5.1 Key Fob as a Transmitter

The preprogrammed demonstration shows how to secure information during data transmission. The red key fob has four push buttons and is powered by a CR2032 coin battery. By pressing any of the four buttons, the information on the pressed button is encrypted and transmitted. During data transmission, the LED on the key fob is flash-ing. The two methods to secure the information before the transmission are KEELOQ Classic and KEELOQ AES. Press button 1 or button 2 to secure the information with KEELOQ Classic and button 3 or button 4 to secure the information with KEELOQ AES. Refer to Figure 2-2.


For more information on KEELOQ Classic and KEELOQ AES, refer to the following Microchip Technology Application Notes:

• AN1259 KEELOQ® Microcontroller-Based Code Hopping Encoder (DS01259)

• AN1265 KEELOQ® with AES Microcontroller-Based Code Hopping Encoder (DS01265)

FIGURE 2-2: KEY FOB WITH FOUR PUSH BUTTONS

2.5.2 Embedded Security Development Board as a Receiver

When the SX1239 Receiver PICtail Daughter Board receives a secured packet, the content of the packet is acquired by the target application microcontroller. Based on the length of the received packet, the target application microcontroller decides what cipher (KEELOQ Classic or KEELOQ AES) to use in securing the data. The decryption process reveals the plain text, and the authentication process verifies whether the plain text contains valid information.

2.5.2.1 KEELOQ® CLASSIC

For KEELOQ Classic, the receiver accepts messages only from a known transmitter. The known transmitters and their latest counters are stored in the Nonvolatile Memory (NVM) space of the microcontroller. If a packet is received from an unknown transmit-ter, the message “KLQ: (serial number) Not Learned!” displays on the LCD as shown in Figure 2-3.

FIGURE 2-3: ERROR MESSAGE OF RECEIVING PACKET FROM AN UNKNOWN TRANSMITTER



To learn a transmitter, press the SW4 button to make the receiver initiate the learning process. The message “Learn mode active” displays on the LCD, as shown in Figure 2-4.

FIGURE 2-4: START LEARN MODE

If the received packet is from a known transmitter, the NVM remains untouched. If a relearn is performed to resynchronize the hop counter of a transmitter, the NVM must be erased first. If no KEELOQ Classic packet from an unknown transmitter is received within 18 seconds, the KEELOQ Classic Learn mode timeouts and displays the mes-sage “Learn mode timeout” on the LCD as shown in Figure 2-5.

FIGURE 2-5: LEARN MODE TIMEOUT

When all slots in the NVM space for transmitters are taken, the learning process fail. Press and hold SW4 button for about ten seconds to erase all transmitter records from the NVM. The message “Memory Erased” displays on the LCD as shown in Figure 2-6. After erasing records from the NVM, reset the board by removing and reinserting J6.

FIGURE 2-6: ERASE TRANSMITTER RECORDS FROM MEMORY


When a KEELOQ Classic packet is received from a known transmitter, the contents of the packet displays on the LCD as shown in Figure 2-7. The LED D7 flashes during a valid packet reception.

Figure 2-7 shows the following information from a sample KEELOQ Classic packet:

• Encoder: KLQ representing KEELOQ Classic

• Serial number of the transmitter: a 28-bit serial number

• Counter (C): a 16-bit number

• Function Code (F): a bitmap of the pressed buttons on the key fob. Number 3 displays if both KLQ buttons (1 and 2) are pressed.

FIGURE 2-7: KEELOQ® PACKET INFORMATION

2.5.2.2 KEELOQ® AES

For KEELOQ AES, it is not required that a transmitter must be known to the receiver before a packet can be accepted. Therefore, there is no learning process for a packet encoded with KEELOQ AES cipher. When a KEELOQ AES packet is received, the con-tent of the packet displays on the LCD as shown in Figure 2-8. The LED D7 flashes during a valid packet reception.

Figure 2-8 shows the following information from a sample KEELOQ AES packet:

• Encoder: AES representing KEELOQ AES

• Serial number of the transmitter: a 32-bit serial number

• Counter (C): a 32-bit counter

• Function Code (F): a bitmap of the pressed buttons, depending on the button pressed on the key fob.

FIGURE 2-8: KEELOQ® AES PACKET INFORMATION



2.6 EMBEDDED SECURITY DEVELOPMENT BOARD HARDWARE SELF-CHECK

A hardware self-check can be performed to ensure the hardware integrity of the Embedded Security Development Board. The instructions for the hardware self-check are displayed on the LCD. The test result is either checked by the firmware and displays on the LCD or verified by user observation.

To initiate the hardware self-check, press and hold the SW1 button before powering up the Embedded Security Development Board. Release the SW1 button only when the message “HDW Self Tests” displays on the LCD screen.

The four individual hardware self-tests are performed in the following sequence:

2.6.1 Button Test

“Button Test” displays in the first line of the LCD display, while the test instructions are displayed in the second line.

Once the required button is pressed, the test instruction message changes for the next push button. Once all buttons have been tested, press SW1 button to move forward to the LED test.

2.6.2 LED Tests

When the LED tests start, the message “LEDs Flashing” displays in the first line of the LCD display. During the tests, the two sets of LEDs are flashing separately, while LEDs from the same set must be flashing together at roughly one second intervals. Once the user verifies the LED test, press SW1 button to move forward to the Real-Time Clock and Calendar (RTCC) test.

2.6.3 RTCC Test

When RTCC test is initiated, the LCD display shows the clock and the calendar. If there is no coin battery installed for RTCC, the time displayed is close to the reset time of January 1, 2012. If a coin battery for RTCC is installed, the time displayed is based on the previously set time, plus the time that has passed. Observe that the clock shows the time in advance. Once the RTCC test is done, press SW1 button to move forward to the SPI test.

2.6.4 SPI Test

The SPI test in hardware self-check is performed on the SPI bus that connects the target application microcontroller and the SX1239 Receiver PICtail Daughter Board. Therefore, the SX1239 Receiver PICtail Daughter Board must be plugged in before starting the test. Once the SPI test starts, the target application microcontroller requests specific information from the SX1239 receiver through the SPI bus. The “Successful” status displays if the expected response is received. Otherwise, expect the “Fail” status message.

Note: If a PICtail daughter board other than the SX1239 Receiver PICtail Daughter Board is plugged into the PICtail connector, the SPI bus may still work, but the SPI test may show a failure status. It is due to the expected values to be received specifically from the SX1239.

Chapter 3. MICRF114 Wireless Remote Key Fob

3.1 INTRODUCTION

The MICRF114 Wireless Remote Key Fob is a demonstration and development platform for wireless security remote control applications. This chapter provides a detailed description of the key fob.

3.2 HARDWARE DESCRIPTION

Figure 3-1 shows the key fob. The enclosure is an off-the-shelf key fob from Polycase (http://www.polycase.com/). The enclosure houses a two-sided PCB.

Appendix A. “MICRF114 Wireless Remote Key Fob Schematics” provides the PCB layout, schematic, and Bill of Materials (BOM).

FIGURE 3-1: MICRF114 WIRELESS REMOTE KEY FOB

3.3 PCB DESCRIPTION

The key fob PCB is a two layer, plated through hole, 1/24 inches (1 millimeter) thick, FR4 material. Figure 3-2 and Figure 3-3 show the top and the bottom view of the PCB. All components, except the coin battery, are on the top side. These components are the PCB antenna, conductive push button footprints (SW1-SW4), LED (LD1), MICRF114 transmitter (IC1), RF matching network (C5-C8, L1-L3), and PIC12LF1840 microcon-troller. A PCB antenna is used in the design for reduced cost and compactness. Refer to Section 3.4 “PCB Antenna Description” for more information on the PCB antenna. An ICSP™ Programming Capability is also available on the board.

Refer to Chapter 6.“Wireless Security Remote Control Development Kit” for suggestions on developing and programming the key fob.


http://www.polycase.com/


FIGURE 3-2: PCB TOP SIDE

FIGURE 3-3: PCB BOTTOM SIDE


3.4 PCB ANTENNA DESCRIPTION

The on-board antenna of the key fob is a meander shaped PCB antenna in which impedance and resonant frequency are determined by electromagnetic (EM) simula-tions and laboratory fine tuning. This design leads to a modest antenna gain (about -18 dBi), which is usual in the case of small PCB sizes. On the other hand, it does not require any external impedance matching component as the impedance of the antenna are set to 50 ohms by simulation and fine tuning.

The designer is cautioned that although this design is constructed to be ETSI/FCC certifiable, the final product may require fine tuning. It is the responsibility of the designer to ensure that the final design satisfies ETSI or FCC recommendations, or both. There are some factors that determine the performance of a PCB antenna, such as the thickness of the copper layers, thickness of the PCB material, choice of PCB material (FR4 as an example), and choice of passive components used.

Figure 3-4 shows the used antenna dimensions on both top copper and bottom copper layers.

The antenna connection has a pin socket for plugging in a wire antenna. This demon-strates a simple and low-cost antenna option. The length of the antenna must be approximately 1/4 wavelength of the frequency of interest.

If a whip or sleeve dipole antenna having an SMA connector must be used instead of the wire antenna, the antenna pin can be replaced with a mating SMA socket by remov-ing the wire antenna pin and using the SMA footprint on the same place.

The Serial Accessory Port supports the following interfaces:

• 3- or 4-wire SPI

• I2C

• USART

The on-board switch, S1, selects these interfaces. Jumpers J7 and J8 connect the pull-up resistors when I2C is selected and the pull-up resistors are unavailable on the daughter board. Software modifications are expected to use those interfaces when different functionalities are assigned to the pins.

For more information on the port pin assignment, refer to the schematic in Appendix C. “Embedded Security Development Board Schematics”.

5.2.3 USB Interface Port

Microchip MCP2200 provides USB to UART support. MCP2200 provides automatic conversion between UART and a full-speed USB 2.0 communication. At the same time, the USB interface port can be used to directly power the Embedded Security Develop-ment Board. For more information, refer to the MCP2200 Data Sheet (DS22228).

5.2.4 PICtail Port

The PICtail port is a 28-pin interface port that supports Microchip's RF-based daughter boards. The PICtail port provides the following interfaces to the daughter boards:

• Power supply

• SPI interface

• Interrupt request lines

• Other digital/analog I/O lines

There are many Microchip accessory daughter boards with a PICtail port connectivity. When unused as one of the components in the Wireless Security Remote Control Development Kit, the Embedded Security Development Board can be connected to any daughter board with a PICtail port and perform different functionalities.

For more information on the accessory daughter boards with a PICtail port, refer to the Microchip website at www.microchip.com.

5.2.5 LCD Display

The Embedded Security Development Board supports a 16x2 character LCD display with backlight. The LCD is controlled by the host microcontroller through the SPI port.

For more information on the LCD display, refer to the “NHD-C0216CZ-FSW-FBW-3V3” specification by Newhaven Display (http://www.newhavendisplay.com).

5.2.6 Real-Time Clock and Calendar (RTCC) Module

The Embedded Security Development Board RTCC module can be used to precisely set and track clock and calendar. The RTCC functionality is achieved with the Microchip MCP795W10 device. The RTCC module is controlled by the host microcontroller through the SPI interface. The RTCC module can be powered either by the 3.3V power from the Embedded Security Development Board or by a separate coin battery when external power is unavailable.

For details on operating the RTCC module, refer to the “MCP795W1X/MCP795W2X SPI RTCC with Enhanced Features and Battery Switchover Data Sheet” (DS22280C) at http://www.microchip.com/MCP795W10.

5.2.7 Push Buttons

The Embedded Security Development Board has two sets of push buttons. Each set consists of four individual push buttons and serves as input to the host and target appli-cation microcontrollers.

The four push buttons for the target application microcontroller are read as a single analog input. Depending on the different ratios of pull-up and pull-down resistor values, the input analog voltages to the master microcontroller are different. Therefore, the pressed button can be identified through the ADC on the target application microcontroller. Such design is used to save I/O pin requirement for the target application microcontroller.

Note: The user must be careful about the PICtail port pins that share different functions of the board. The user must also check the schematics before assigning functions to any port pin.


http://www.newhavendisplay.com

http://www.microchip.com/MCP795W10



For more information on the design of the push buttons, refer to the schematics in Appendix C. “Embedded Security Development Board Schematics”.

The four push buttons for the host microcontroller are four separate digital inputs to the slave microcontroller due to the abundant I/O pin availability. All buttons are assigned to the individual interrupt lines of the microcontroller and are not driven by external pull-up circuitry to save on power consumption. The user software must enable the PORTB pull-ups of the microcontroller before evaluating the button state.

The MCLR push button is connected to the RE3/MCLR pin of the target application microcontroller. The RE3/MCLR pin of the target application microcontroller is one of the SPI lines that control the host microcontroller. When the target application and host microcontrollers are interconnected, the RE3/MCLR pin of the target application micro-controller is configured to be a normal digital I/O pin. Therefore, the MCLR push button is ineffective. However, if an SPI communication is not required between the target application and host microcontroller, the pin can be configured as Reset by using the MCLR push button.

5.2.8 LEDs

There are two sets of LEDs controlled by the target application and host microcontrol-lers, respectively. The target application MCU controls a set of four LEDs through the digital output pins. The host MCU controls a set of seven LEDs through digital output pins. The two sets of LEDs are useful in the demo or debugging process.

In addition, two LEDs, D15 and D16, on the left section of the Embedded Security Development Board are used to identify the TX and RX operation of the MCP2200. LED D2 indicates the power availability. These LEDs cannot be controlled by either the target application or the host microcontroller.

5.2.9 Power Supply

The Embedded Security Development Board is powered by one of these two sources:

• USB port

• External 3.3V power source through GND and +VEXT connectors

Set jumper J6 to pins 1-2 to power the Embedded Security Development Board from the USB port, and set J6 to pins 3-4 to power from an external power source.

When the USB port is used to power the board, the input voltage is stabilized by Microchip MCP1703, 250 mA, 3.3V, and low quiescent current LDO regulator (U3).


5.2.10 ICSP™ Programming Capability

Figure 5-2 shows that there are two ICSP programming/debugging ports on the Embedded Security Development Board. The ICSP port on the left side, J4, is used to program the host microcontroller. The ICSP port on the right, J5, is used to program the target application microcontroller.

Chapter 6. Wireless Security Remote Control Development Kit

6.1 INTRODUCTION

This chapter provides recommendations regarding the development of an RKE solu-tion on the Wireless Security Remote Control Development Kit. General design consid-erations are also provided for both the transmitter and receiver side.

6.2 DEVELOPING WITH THE KEY FOB AS TRANSMITTER

To modify the hex code in the key fob, the developer must open the red plastic enclo-sure. The ICSP port is available on the key fob PCB as six through-hole pads. The developer can access the MCU either by soldering a 6-pin header into the holes or by pushing the ICSP header in the ICSP through-hole pads. Slightly tilt and force the ICSP header to ensure proper connection and then start programming. Be careful as not to make short to the coin battery.

As a secured RKE system, KEELOQ® security keys, especially the manufacturer key is essential to the security of the whole system. It is highly recommended to use the code protection of the PIC® MCU memory.

The Microchip RKE demo uses pulse-width modulation (PWM), driven by interrupt, in data whitening procedure. The achievable transmission data rate over the air is tightly related to the operation speed of the microcontroller. Higher data rate requires faster processing speed. Higher transmission data rate may reduce the total active time for each transmission. However, higher microcontroller processing speed generally results in higher current consumption. The real application may need a compromise between higher data rate and faster processing speed to achieve optimal battery life.

6.3 DEVELOPING WITH THE EMBEDDED SECURITY DEVELOPMENT BOARD AS RECEIVER

The Embedded Security Development Board acts as a receiver in the Wireless Secu-rity Remote Control Development Kit. The target application microcontroller on the right side of the development board is the driving host for the receiver. All data receiving and KEELOQ security functionalities are performed by the target application microcontroller. On the other hand, the host microcontroller is mainly used to drive the LCD display in this demo.

If the developer decides to develop the application only on the target application micro-controller, intercommunication between the target application and the host microcon-troller can be ignored. The prototyping area under the four push buttons of the target application controller can be used to prototype the application.

Note: When testing the key fob transmission with an open plastic enclosure, avoid touching the PCB area with your finger. For simplicity, all key fobs in the demo share the same serial number.



Similar to the transmitter, when Continuous mode is used to receive data, the data rate is tightly associated with the processing speed of the microcontroller. Unlike the trans-mitter, which is usually powered by battery, the receiving side is usually powered by main power, and power consumption is of less concern. It is possible to run the micro-controller faster to achieve higher data rate.

On the other hand, if the developer also decides to use the host microcontroller, then the intercommunication between the two microcontrollers may need attention. The host microcontroller is an SPI slave, and thus requires a faster response to the SPI com-mand. Generally, if no SPI delay is applied by the target application controller side, the operation speed of the host microcontroller must double the speed of the target appli-cation microcontroller.

Normally, the MCLR button is not functioning as a Reset button due to the RE3/MCLR pin is configured as a general-purpose input and is used for the Master-Slave commu-nication. To debug the application, the Reset functionality must be enabled by modify-ing the appropriate Configuration bit and installing R27. In this case, communication between the Master and the Slave MCUs is lost.
